Year 7 Maths — Visualising solid shapes

Count the faces, edges and vertices of a solid, tell flat surfaces from curved ones, and say what a solid looks like from another direction.

Name: ________________________

Before you start

A cube, drawn on flat paper. Find out what each part of it is called.

1234
  1. 1. The top face
  2. 2. The front face
  3. 3. An edge
  4. 4. A vertex

A cube has 6 faces, 12 edges and 8 vertices — and you can only find some of them on the drawing, because three faces and three edges are hidden round the back.

  1. 1.How many edges does a square pyramid have?

  2. 2.How many faces does a cube have?

  3. 3.How many vertices does a cuboid have?

  4. 4.How many edges does a cube have?

  5. 5.You look straight down on a cylinder standing upright on a table. What shape do you see?

    • a) A triangle
    • b) A rectangle
    • c) A square
    • d) A circle

  6. 6.How many faces does a triangular prism have?

  7. 7.Match each solid to the number of faces it has.

    • Triangular pyramid
    • Triangular prism
    • Cube
    • Pentagonal prism
    • Hexagonal prism
    • 8
    • 7
    • 6
    • 4
    • 5

  8. 8.How many vertices does a triangular pyramid have?

Answer key — Year 7 Maths — Visualising solid shapes

  1. 1. 8
  2. 2. 6
  3. 3. 8
